+One more thought on this: what should "*+tag" do if the search buffer is\r
+still filling?\r
+\r
+As it stands this is a substantial change: previously you could\r
+look at the first few threads to make sure the query was doing what you\r
+expected and then tag all the matching threads. Now you would have to\r
+wait for the buffer to fill and there is not even a clear indication to\r
+the user of when that happens (except scroll to the bottom and see if it\r
+says "End of search results.")\r
